uLtimate™ Connection Series

The Grant Prideco™ uLtimate Connection Series is specifically designed to provide increased torque capacity. This is achieved by using high strength materials and making-up the connection to a higher torque level. Even at this higher make-up torque level, the fatigue-resistant thread form and cold-rolled thread roots increase fatigue life above that of standard GPDS™ and XT™ connections. The high strength properties of the uLtimate Series increase performance, and the ruggedness of these connections extends service life.

Benefits

Increased torque capacity (+26%)

Approximately twice the relative fatigue resistance over standard GPDS™ and XT™ connections

Ruggedness of these connections extends service life

Applications

Shale Plays

As horizontal hole sections have increased in length, so has the demand for a drill string with higher torsional capacity. uXT has been one of the key technologies that has resulted in the success of shale drilling programs by providing the increased drilling torque and hydraulic performance necessary to drill these extended horizontal sections.

Extended Reach Wells

Operators are now demanding even more torque to reach new targets. The uLtimate Series has enabled operators to expand the industry's drilling envelope. It has helped in successfully drilling world-class ultra-extended reach wells, including several world records.

InterchangeabilityuLtimate Series connections are interchangeable with their GPDS and XT connection counterparts, so current inventories of tools and accessories can still be used.

Xmark™ BenchmarkThis proprietary refacing benchmark is placed on the external bevel of the connection, and serves as a 360º visual reference for misaligned refacing without the removal of thread protectors.

Identification GrooveThis unique identification groove visually identifies the connection as an uLtimate Series connection. It is remachined as part of the chase and face operation.
